I have a database "Customer" with about 60Gb of data. I know I can backup and restore, but this seems too slow.
Is there any other option to duplicate this database as "CustomerTest" as fast as possible (even fastar than backup/restore) - better if in one operation (something like "copy database A to B")? I would like to run this everyday, overnight, with minimal impact to prepare a test environment based on production data.
Hum, I don't know exactly how to do it, but on Linux, you could put the "Customer" database in a tablespace which resides on a BTRFS filesystem. BTRFS can do a quick "snapshot" of the filesystem and you can then set things for "incremental backup", as talked about here: https://btrfs.wiki.kernel.org/index.php/Incremental_Backup . From some reading, btrfs is a performance dog compared to others.
